Programming oven temperature
HP 5890 oven temperature programming allows up to three ramps, in
any combination of heating or cooling. Keys defining an oven temperature
program include:
INIT TEMP
A setpoint temperature value at which the oven is
maintained at the beginning of a temperature•programmed
run. This is also the temperature to which the oven returns
at termination of the temperature•programmedrun.
When not in a run, the setpoint value for
INIT TEMP
equals
OVEN TEMP
.
INIT TIME
Time for which oven temperature is held at
INIT TEMP
.
RATE
Rate at which the oven is to be heated or cooled.
FINAL TEMP
Temperature the oven attains at the end of a heating or
cooling ramp.
In a multiple•ramptemperature program, final
temperature for one ramp is also the initial temperature
for the next ramp.
FINAL TIME
Time period over which oven temperature is held at
FINAL TEMP
.
In a multiple•ramptemperature program, final time for one
ramp is also the initial time for the next ramp.
total elapsed time for a run cannot exceed 650 minutes: at 650 minutes,
the run terminates and oven temperature recycles to
INIT TEMP
. To know
calculated total length of time anticipated for a run,
TIME
is pressed
repeatedly until a NEXT RUN display is obtained.
